ANT203Y1 Lecture Notes - Lecture 3: Theodosius Dobzhansky, Population Genetics, Zygosity
Document Summary
Posted online so you can look further into this opportunity as a research venture. Mendel work led us into the 1900s, where people started getting more curious regarding this relm. Genotype: what is actually encoded in the dna. Phenotype is the physical expression of what is encoded. 1930s and 1940s---incorporating classic selection and evolutionary principles with modern genetics. Were looking to find broader concepts to create a more cohesive. Julian huxley: not much of a researcher but loved bringing people and resources together. Fruit flies are great for testing as they breed extremely quickly and theyhave a short life span. He described mutations as having new variation in populations. There were harmful mutations such as fruit flies born without mouths, and also beneficial mutations such as larger wing span. Species could interact due to variations and mutaions which could create a better compatability across species. You can have a change in frequency due to chance events and totally random processes.
